BOSTON, April 18, 2017 (GLOBE NEWSWIRE) -- Paratek Pharmaceuticals, Inc. (Nasdaq:PRTK) announced today that data from its omadacycline clinical and microbiology programs will be presented at the annual meeting of the European Congress of Clinical Microbiology and Infectious Diseases, ECCMID 2017, to be held April 22 – 25 in Vienna, Austria. Paratek is a biopharmaceutical company focused on the development and commercialization of innovative therapies based upon tetracycline chemistry.

“We will have thirteen posters or presentations at ECCMID, which continue to demonstrate the breadth of the clinical program supporting the development of omadacycline. With these data, we continue to deepen our understanding of its utility against relevant pathogens and serious community-acquired infections such as ABSSSI and CABP,” said Evan Loh, M.D., President, Chief Operating Officer, and Chief Medical Officer, Paratek. “Notably, we will share the results from our Phase 3 once-daily oral and IV ABSSSI study, as well as the detailed analysis of microbiology results from the same study. With the growing challenge of antimicrobial resistance, additional examination of these data further reinforces the potential of omadacycline, particularly when resistance is of concern.”

About Paratek Pharmaceuticals, Inc.Paratek Pharmaceuticals, Inc. is a biopharmaceutical company focused on the development and commercialization of innovative therapies based upon its expertise in novel tetracycline chemistry. Paratek's lead product candidate, omadacycline, is the first in a new class of tetracyclines known as aminomethylcyclines, with broad-spectrum activity against Gram-positive, Gram-negative and atypical bacteria. In June 2016, Paratek announced positive efficacy data in a Phase 3 registration study in acute bacterial skin and skin structure infections (ABSSSI) demonstrating the efficacy, general safety, and tolerability of intravenous (IV) to once-daily oral omadacycline compared to linezolid. In April 2017, Paratek announced positive efficacy data in a Phase 3 registration study in Community-acquired Bacterial Pneumonia (CABP) demonstrating the efficacy and safety of intravenous (IV) to once-daily oral omadacycline compared to moxifloxacin. A Phase 3 registration study in ABSSSI comparing once-daily oral-only dosing of omadacycline to twice-daily oral-only dosing of linezolid was initiated in August 2016. Top line data from this study are expected as early as the end of June 2017. A Phase 1B study in uncomplicated urinary tract infections (UTI) was initiated in May 2016 and positive top-line PK proof-of-principle data were reported in November 2016. The company plans to begin enrolling patients in a proof-of-concept Phase 2 study in complicated UTI as early as December 2017.

Omadacycline is a once-daily oral and IV, well-tolerated broad spectrum investigational antibiotic being developed for use as empiric monotherapy for patients suffering from serious community-acquired bacterial infections, such as acute bacterial skin and skin structure infections, community acquired bacterial pneumonia, urinary tract infections and other community-acquired bacterial infections, particularly when antibiotic resistance is of concern to prescribing physicians. Omadacycline has been granted Qualified Infectious Disease Product designation and Fast Track status by the U.S. Food and Drug Administration for the target indications.

In October 2016, Paratek announced a new cooperative research effort with the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) to study omadacycline against pathogenic agents causing infectious diseases of public health and biodefense importance. These studies are designed to confirm dosing regimens and assess efficacy of omadacycline against biodefense pathogens, including Yersinia pestis (plague) and Bacillus anthracis (anthrax).

Paratek's second Phase 3 product candidate, sarecycline, is a well-tolerated, once-daily oral, narrow spectrum tetracycline-derived antibiotic with potent anti-inflammatory properties for the potential treatment of acne and rosacea in the community setting. Allergan owns the U.S. rights for the development and commercialization of sarecycline. Paratek retains all ex-U.S. rights. In March 2017, Allergan announced positive efficacy data in two identical Phase 3 registration studies in acne vulgaris demonstrating the efficacy and safety of once-daily, oral-only sarecycline compared to placebo.
